Research On Classroom Teaching Of High School Physics Driven By Open-ended Questions

In order to cope with the social change and the development of The Times,the basic education has put forward new requirements for the cultivation of students' scientific inquiry ability and problem-solving ability.It promotes the reform of high school physics classroom teaching.Teachers should hide open questions in the natural and living situation,which can not only stimulate students' curiosity to explore the nature,but also guide students to analyze,explore and solve problems with scientific methods,and finally realize the teaching goal of cultivating students to explore the world from the view of physics.In class teaching,the introduction of open questions will inevitably bring about such defects as the complexity of the problems and the concealment of the known conditions.If the original questions with high openness are directly introduced,it will make the physics teaching even more difficult,which itself has the dilemma with few class hours and students' learning difficulties.With the rise of the problem-driven teaching method,teachers begin to re-examine the role of open questions in class teaching.Under the guidance of Makhmutov's problem teaching theory,Constructivist theory and Motivation theory,in this paper,we discuss the teaching model and teaching strategy of problem-driven teaching by open problems and the principle and strategy of problem design.On this basis,design of open problems for problem-driven teaching is studied,and two kinds of open-problem-driven teaching practices are carried out.In the design of open problems,by combining the existing two design methods of open problems,the third design method of open the open problems with a certain level of openness is obtained according to students' cognitive level.Through practical research,it is concluded that it is feasible and necessary to adopt open-problem-driven teaching in high school physics class,and it is also needc to pay attention to students' cognitive level and characteristics,as well as to solve the problem of low classroom efficiency.
